Feature: 1. Lens and Aperture: This automatic optical level has 32X magnification lens and large aperture, which can operate within a range of 393 feet and obtain clearer images even in low light conditions. 2. High Accuracy: This level adopts FMC optical coated lens to ensure high imaging quality, accurate measurement, and excellent accuracy, with 1.0mm standard deviation per kilometer (dual way level). 3. Stable Measuring: Self leveling magnetic damping compensator with transport lock can quickly stabilize the system and reduce the impact of vibration on the construction site, providing accurate level measurement. 4. Good Protection: The level adopts aluminum alloy shell with IP55 protection rating, which has good vibration resistance, dust resistance, and waterproofing, and can adapt to complex working environments. 5. Screw and Prism: This automatic optical level features 3 pieces accurate leveling screws and a 90 degree prism, which can quickly align circular bubble bottle to set the level tool. 6. Wide Application: This 32X optical level is suitable for construction engineering measuring, deformation subsidence monitoring, mine measuring, road measuring, bridge and tunnel measuring, etc. Specification: Item Type: Automatic Optical Level Material: Aluminum Alloy Telescope Magnification: 32X Standard Deviation Per Kilometer: 1mm Level Accuracy: 0.3 Second Level Compensation: 15 Minute Protection Rating: IP55 Dustproof Waterproof Lens: FMC Optical Coating.
